Ice-Blue Dial
The ice blue dial features a guilloché rice-grain motif. This rosette-like design is distinctive for its three-dimensional, repeating geometric pattern that extends across the surface of the dial starting from the small seconds counter at 6 o’clock. The minute track is surrounded by a filet sauté with crimped pattern, which is also guilloché. With the introduction of a dial created via guillochage, or engine turning – a technique that uses a turning tool to sculpt a pattern into a surface – Rolex is pursuing the course it has set for the Perpetual collection as a tribute to the classic art of watchmaking infused with the brand’s know-how and creativity. This exclusive dial bears the same Arabic numerals 3, 9 and 12, the same faceted hour markers and the same hands as that of the 18 ct gold versions. This exclusive dial colour can be found only on the Day-Date, the Cosmograph Daytona and the Perpetual 1908.
Domed and fluted bezel
This elegant and understated watch features a slim case crowned with a bezel that is part domed and part finely fluted – the lower part being given an elegant fluting and the upper part domed.
Platinum
Rare and precious, platinum is striking for its silvery whiteness and vibrant luminosity. It is among the densest and heaviest metals in the world, distinguished by unique chemical and physical properties such as exceptional corrosion resistance. Paradoxically, it is also soft, elastic and highly malleable, which makes machining and polishing especially difficult, demanding an extremely high degree of skill. Rolex always uses 950 platinum, an alloy consisting of 950‰ (thousandths) platinum, painstakingly crafted in-house by the fine metalworkers at Rolex. The noblest of metals for the finest of watches.Model Availability
